This is a mutually exclusive event because you can't choose both at the same turn you can only pick one or the other. so we add the event chances together,
5/35 + 10/35 = 15/35 or reduced 3/7

a taxi ride costs 40 dollars for the first 500 meters and each additional 300 meters (or a fraction thereof) adds $3.50 to the f
Colt1911 [192]

Answer:

$ 71.5

Step-by-step explanation:

firstly kilometer to meters

<em>1 km = 1000 m </em>

therefore 3 km = 3000m

for the first 500 = $40

hence deduct the 500 from 3000m

3000 - 500 = 2500

now find out how many 300m go into 2500

2500 / 300 = 8.33

which is rounded up to 9

therefore the total amount is :

40 + 9 * 3.5

<u>= $71.5</u>

so remove 287 from 367

367-287=80

Then divide by 5

80/5=16

so, x=16

Simplify -6(6+10+6v)
UkoKoshka [18]
<h3>Answer is -96-36v</h3>

Work Shown:

The "6+10" in the parenthesis combines to 16. So we really have -6(16+6v)

Use the distribution rule. Multiply the outer -6 by each term inside

-6 times 16 = -96

-6 times 6v = -36v

Put together, we have -6(16+6v) = -96-36v

Answer:

8) 0.46

Step-by-step explanation:

100% - 54% = 46%

46%/100 = 0.46
